3 Claims.

It is the object of this invention to utilize inherently weak material, such as wood veneer or fibre board, in the construction of a shipping container having a novel arrangement of metal binding strips whereby greatly increased strength and durability is obtained.

A further object is to provide an unusually inexpensive container constructed largely from wood-and adapted to be shipped in flat, compact form and to be readily set up or assembled in box form for use. 7

Other objects are to provide a container adapted to be constructed from wood, without the use of cleats, and being light in weight and readily adaptable for use in the construction of boxes of various sizes and cross sectional shapes, such as circular, hexagonal, octagonal, etc, and having large, smooth and plane exterior surfaces and fiushends adapted to receive printing.

In the accompanying drawing which illustrates the best form of my device at present known to Figure 1 is a plan view of the four thin sides or panels of the containenlaid flat, and with the binding strips attached;

Fig. 2 is an end view of the same;

Fig. 3 is a fragmentary section, on an enlarged scale, taken on the line 33 of Fig. 1;

Fig. 4 is an end view of the container with the top secured in closed position;

Fig. 5 is a perspective View of the container with the. cover in open position and Fig. 6 is a fragmentary, horizontal section, taken on the line 66 of Fig. 5 and on an enlarged scale.

The box has a front panel '7, bottom panel 8, back panel 9 and top panel 10, preferably constructed from Wood veneer, and connected together by continuous binding strips 11 extending across the grain of the wood at each end of said panels. As shown in Fig. 6, the binding strips extend equally upon the outer and inner surfaces of the several panels '7, 8, .9 and 1G and integral with the strip is a flange 12 formed from two thicknesses of the metal. The otherwise. free, edge extremities of the strips 11 are firmly secured to the panels '7, 8, 9 and 10 by a series of teeth 13 cut from said extremities and impressed into the said panels, as best shown in Fig. 3. It

will be evident that the edges of each strip 11 are located directly opposite each other so that the teeth 13 may be formed and impressed into the panels by dies working simultaneously from opposite surfaces.

Ends 14 of the container are constructed from Paul, Mimic, assignor to St. Paul, Minn,

relatively thick boards and in each of the four edges of each end is a groove 15 to receive one of the flanges 12. The ends 14 are of such thickness and the grooves 15 are so located therein that the outer surfaces of the ends are flush with the ends of the panels 7, 8, 9 and 10.

The flanges 12 are cut away at the corners of the box to permit the strips 11 to be bent as the panels 7, 8, 9 and 10 are moved from the flat position shown in 1 to the angular positions required for the erection of the box. In the construction of the box, the panels '7, 8, 9 and 10 are assembled and secured together as shown in Fig. 1 1 and the ends 14 and thin panel assemblies are shipped by the manufacturer to the user or shipper in flat, knock-down condition. The boxes are erected by merely placing the ends in engage ment with the flanges 12 of the bottom panel 8 and then the panels '7 and 9 are folded upwardly to engage the flanges 12 thereon in the grooves 15 at the front and back edges of the ends. The

sides may be secured in this position by driving nails 16 through the metal binding strips and into the ends, as indicated in Figs. 1 and 6. The goods to be carried may now be placed in the container and the top panel 10 is finally closed and secured in closed position, either by driving additional nails, or otherwise, as by a pair of wire fasteners 1'7 formed with eyes at their ends to receive nails 18 which are driven into the ends 14 through the top panel 10 and front panel 7.

The container of this invention is unusually strong and durable notwithstanding the fact that it is largely constructed from thin, light material. 1 By extending the metal binding strip inward from the flange l2 and securing the inner extremity to the thin panels at points where the ends 14 retain the teeth13 in engagement with the panels, I am able to secure ample strength while utilizing light gauge metal which is inexpensive, easy to handle and requires little power for the formation of the teeth 13. The weight of 1 the contents of the, container, tending to force the ends outward, is sustained by the flanges 12 of double thickness and by the arrangement whereby said flanges distribute the. outwardly directed force to the teeth 13 engaging. the inner sides of the panels 7, 8, 9 and 10, this force being in the formof tension, rather than compression, on the thin metal binding strip. Bendingv of the flanges and buckling of the thin metal isthus avoided and the economies and strength resulting from this arrangement are important features of my container.

Having described my invention, What I claim as new and desire to protect by Letters Patent is:

1. A box comprising, sides constructed from thin material, relatively thick ends formed with grooves adjacent to said sides, metal binding strips embracing the ends of said sides and extendingupon the inner androuter surfaces thereof, flanges formed integral with said binding strips and projecting into said grooves and means connecting the edge extremities of said strips to said sidescomprising a multiplicity of teeth integral with said metal strips spaced apart longitudinally thereof and impressed into said thin sides.

2. A box comprising, sides constructed from thin sheet material, relatively thick ends formed with grooves adjacent to said sides, metal binding strips embracing the ends of said sides and extending upon the inner and outer surfaces thereof, flanges formed from two thicknesses of said binding strips and projecting into said grooves and means connecting the edges of said strips at points inward beyond said flangesto said sides.

3. A box comprising, sidesdisposed in edge to edge relation to each other, ends having edges abutting the inner surfaces of said sides and said edges being formed with grooves adjacent to said sides, metal binding strips embracing the ends of said sides and extending upon the inner and outer surfaces thereof, flanges formed from a fold of vtwo thicknesses of said binding strips, projecting into said grooves and means connecting the edges of said strips to said sides at points inward beyond said flanges.
